| titleOfInvention | Nano red phosphorescent catalyst, preparation method and application in degradation of dye in water and photocatalytic water hydrogen production |
| abstract | The invention provides a preparation method of a nano red phosphorus photocatalyst, which comprises the steps of weighing sodium hypophosphite and boric acid according to a certain molar ratio, and then grinding the sodium hypophosphite and the boric acid to obtain a precursor mixture which is uniformly mixed; then sintering at a low temperature of 200-400 ℃ in an inert atmosphere; and after sintering, centrifugally washing and drying in vacuum to obtain the nano red phosphorescent catalyst. According to the invention, the boric acid is added into the sodium hypophosphite to greatly improve the yield of red phosphorus, and the prepared nano red phosphorus photocatalyst has the advantages of smaller particle size, larger specific surface area, better stability and more excellent visible light photocatalytic degradation of organic pollutants in water and hydrogen production activity by water photolysis. |
